v3->v4:
- simplify splitter logic (Joerg)
- declare supported page-sizes in the iommu_ops, without extending iommu_register (Joerg)
- iommu_unmap should now return bytes too (Joerg)
- don't cache min_pgsize anymore (Joerg)
- handle cases when ->unmap() actually unmaps more than requested (Joerg)
- unroll iommu_unmap completely in case it fails (KyongHo)
- use size_t for size parameters (KyongHo)
- add a patch to remove the bytes->order->bytes conversion we had
- rabase to master branch of the iommu tree (Joerg)
v2->v3:
- s/KB/KiB/ (David W)
v1->v2:
- split to patches (by keeping the old code around until all drivers are converted) (Joerg)
Tested with OMAP3 (omap3isp) and OMAP4 (rpmsg/remoteproc).
Compile tested with X86_64.
